low-level event question

[xarris_]

Hi. This is part of my code, and I need to add some functionality.

else if(command.getCommandType() == Command.OK)
		{
			int index = list.getSelectedIndex();
			switch(index)
			{
			case 0:
				newTags = new Tags(this);
				displayMgr.pushDisplayable();
				display.setCurrent(newTags.list);
				break;
.
.
.

I want to do the same when the RIGHT_KEY is pressed, that is create a Tags and set its list as current. Moreover, when i click LEFT_KEY (after i clicked the right one) I want to go back. Can anybody help? I read about the Canvas class but couldn't get it...
Thanks for any help.

You can detect the left and right soft keys by the keyCode, provided with the keyPressed() method of the Canvas.

The value -6 is assigned to the LEFT_SOFTKEY_CODE, while -7 is assigned to the RIGHT_SOFTKEY_CODE. These values are presented on all Nokia phones, and even on some phones from the other vendors.

Actually i want to use the right and left from the 5way navigation key. But anyway, my problem is more on the implementation than to the code that is assigned on the keys. Can i use directly "if" statements in the commandAction method, that will check the value of the key pressed?

With the high-level UI (Forms, Lists, Commands) that you are using you don't have low-level access, so you don't have a way to react to specific keys.

If you use a Canvas you have the keyPressed() method that will tell you exactly what key is pressed, but then you have to make your own GUI (your own Lists and Forms drawn on a Canvas).

You can sort of mix high-level and low-level using a CustomItem (MIDP 2.0 only), but then you will only get the low level events if your CustomItem has the focus.
